These have been scripted conversions then cleaned up by hand as
there was no consistency to the formatting of the license headers in
the common/ directory. Author information was also removed (it's in
the git history) and so now the header format is consistently:
##/bin/bash

Ext4 will want to use dmhugedisk infrastructure for testing resize
bugs. Ext4 fs images are rather sparse (especially with smaller
block sizes) so the current chunk size of 512 sectors leads to large
space consumption. Allow test to specify chunk size.

Make sure that we can handle multiple bmbt records mapping to a
single rmapbt record. This can happen if you fallocate more than
2^21 contiguous blocks to a file.
(Also add some helpers that can create huge devices with some
dm-zero and dm-snapshot fakery.)
